A spring with constant speed of 3.5x10^4 N/m is initially @ its equilibrium length. (a)How much work must u do to stretch the spring 0.050 m? (b) How much work must you do to crompress it 0.050m?

• Physics -

Energyinspring= 1/2 k*deflection^2

you are given the deflection, and k.

• Physics -

(1/2)(3.5x10^4 N/m)(0.050m)^2
